It’s been about a month now since Samsung’s big New York Galaxy S 4 launch event, which means that it’s finally time for details on the phone’s US retail availability to start arriving. We just saw AT&T get started with pre-orders, and today Samsung follows up with its own announcement of the GS4’s launch on carriers in the States, joined by a few of those companies chiming-in with their own details on just when their customers will be able to get their hands on the Android flagship.

Samsung itself doesn’t really have anything new to say in today’s announcement. It goes over the details of many of the GS4’s features – just like it did at some length during last month’s launch – and mentions that the phone will be coming to AT&T, Sprint, T-Mobile, Verizon, U.S. Cellular, Cricket, and C Spire.

What we’re more concerned with are the specifics for those carriers. Like we already saw, AT&T has the GS4 starting at about $200 on-contract for the 16GB model, with pre-orders shipping April 30.

Today Sprint shares news of its own pre-orders, which will begin tomorrow. New subscribers will be able to get the GS4 at a discount, only paying around $150 for the phone on-contract; existing Sprint users will pay $250, instead. The Sprint GS4 arrives on April 27.

And then there’s T-Mobile. While it was previously talking about May 1 availability, online orders will be getting started early, on April 24. With no more subsidies, the GS4 will sell for about $150 upfront, with monthly $20 payments for the next two years.
